When the sleeve 15. is

rotated it causes the washers 12 and 16 to,

forcedjagainst the upper and lower edges, respectively,i of the eye 5 so that resistance will be'oifered to relative movement of the butts 4 and 6 about the pintle 9, and the door (not shown) to which the l fi l ge is connected v will remain intthe positionto which it" has beenmoved, I, I

The pintle 9 is held the pin'IQ against rotative inovement'bothlwhen screwing the l sleeve 14 into place and when e1 aerating the hinge, thus permitting the sleeve to be readily screwed into place, andreducingthe tend encyof the same to be rotated through move f ment of the hinge butts,

In order to lock the sleeve against 'ijo tation andto provide a finished appearance,

to the lower end of the 'hinggl provlde "a tip 17 that is threadedinteriorly: and is fprcf-- v vided with a hexagonal wrench-engaging surface 18. Upon screwing of thetip 17 to p st tion its upper edge will bebrought against the lower edge of the eye 8 and'th ereby serve asa jam nut, V l v The pin 10can be dispensed with, ifdesired, since, when the parts are in assembled. relation, the extended frictional contact betweenthe shoulder 13 and the upper end. of"

the knuck1e'7, togetherwiththe threaded en but is provided for'the purposeoi securing no u gagement of the pintle with the nut 14:, will hold the pintle against rotative movement relative to the knuckles 7 and 8.

It will be observed that the pintle-receiving members are in stable supporting relation with one another, due to the close assembly and contact of the parts, so that there will be no tilting of the hinge members relative to one another, resulting in transverse strains upon the pintle. In the ordinary type of door hinge, where pintles are vertically disposed, this is of importance, for any unstable relation of the pintle receiving portions relative to one another would result in sagging of the door, with a tendency to distort the relations of the hinge members and impose a transverse strain upon the pintles.

The pintle 9 is flattened at 19, and the washer 16 correspondingly shaped, so that the washer will not rotate relative to the pintle or the butt 6, and there will therefore be no tendency for the sleeve 14 to become un-- screwed when the butt a is swung about the pintle.
